EXPANDING FILING POCKET.

incsnvo.

To all whom it may concern:

Be known that I, ALVAH BUSHNELL, J12, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in EX- pandingFiling Pockets, of which the fol-1 lowing is a specification.

My invention relates to a new and useful improvement in filing walletsor cases, expanding envelopes, paperpockets and the like, and has forits object to provide an expansible wallet, filing case or pocket withend flaps or wings secured to one of the sides to permit expansion ofthe wallet or case.

Another object of the invention is to pro vide in a device of thecharacterstated flexible end flaps or wings carried by a side wall andslida-bly registering with a chamber or pocket in the other sidewall,'said end flaps or wings having non-flexible ends to prevent theiraccidental withdrawal from the pocket or chamber. 7 i

A further object of the invention is to stiffen the end flaps or wingsthroughout the major portion of their lengthat their inner ends toprevent accidentalwithdrawal from the pocket in which they are insertedand to strengthen the upper edges of said flaps; and also to providelocking means to prevent the withdrawal of the flapsor wings from thepocket or chamber With these ends in view, this invention consists inthe details of construction and combination of elements hereinafter setforth and then specifically designated by the claims.

In order that those skilled in the. art to which this inventionappertains, may understand how to make and use the same, I will describeits construction in detail, referring by numerals to the accompanyingdrawings forming a part of this application, in

Fig. 1, is a fragmentary perspective view of a filing case or expandingwallet in a relatively closed position embodying 'my improvements, aportion of the end flap being broken away to plainly illustratetheconstruction.

In carrying out my invention as here embodied, 2 and 3 represent thetwosides or side walls of a filing case or Wallet or similarideviee, theside 2 generally being the back and the side 3 the front. These sidesare connected by an inwardly, foldable or bellows bottom having bend orcrease permit expanding v and collapsing thereof. a 1

I One of the sides as 2, is provided with end .fla s or wings 6, thefree ends of which" sli ably or adustably engagethe other side 3, saidside preferably being provided with from one side to the other when thefiling;

case is fully expanded, while the free ends which slide within thepocket are stifi and these stiffened ends should be longer. thanpockets,but if found desirable openings 13 i a this the flexibleportions to prevent their accidental withdrawal from the pocket so thatthe major portions of said end flaps or wings are stiff. r

In actual practice the side 2 which is used as the back is made oftwothicknesses of material 8 and 9 between which the end flaps or wings 6are secured while the side 3 which become the front is made of twothicknesses of material 10 and 11 throughout a portion of its heightonly one of said thicknesses of materialextending from the bottom to apoint intermediate the upper and lower edges of the side 3 leaving theupper portion of the side 3 of single thick-' ness to form a flexibleflap 12 which. may

be easily and readily bent forward for-in sertion ofpap'ers of otherarticles'in the filing case. The two sheets or thicknesses of material10 and 11 are not attached to each other for a distance equal to theheightor width of the end flaps or wings so as to form the pocket 7 inwhich said end flaps slide. V

' The end flaps or wings 6 may be moved in and out of the pocket byinserting the thumbs or-"fingers'in the open ends of-the may be formedin the other sheet or thickness of' material 11 of the side 3, oneadjacent each end so that the thumbs or fingers may be pressed againstthe end flaps or wings to move them in either direction and may bereadily accomplished if the thumbs or fingers are dampened slightly.

The free or sliding ends of the end flaps or wings'6 are stiffened byattaching thereto an additional sheet of thickness of material lflwhich'should extend throughout the majorportion of their length toprevent them being accidentally withdrawn when in use. The edges of theend flaps or wings 6, particularly the upper edges may be strengthenedby folding a portion .of the material upon itself along the upperedgesof said end'fiaps asindicated by the refer ence numeral 15, Fig. 3. Byconstructing the end flaps in this manner the likelihood of theirbeingtorn-in the filing caseis reduced to a minimum. a o

In the construction shown 111 Fig; 6 the end of one of the flaps 6 has'atongue 16 formed therewith terminating in a locking end 17 while the endof theopposite flap has a slot 18' formed therein and adapted to receiveand permitthe sliding therein of the tongue 16. The tongue is insertedin this slot by folding in the projecting portions of the. head,afterwards by turning these ends back to their original positions 'thetongue will be prevented from withdrawal from the slot, thus limitingthe. movement of the flaps 6 and preventing their withdrawal from thepocket or chamber 7 as will be readily understood.

made of single ply material withthe side wings 6 formed as an integralpart of the side wall 2, and if found desirable may be provided with thestiffening material here inbefore referred to, but which is notabsolutely essential and in this form the pocket 7 is produced bysuperimposing a sheet of material 25 on the outside of the side wall 3and securing the former to the latter along two of its opposed edgessuch as'the top and bottom edges as indicated at'26, the ends of saidsuperimposed sheet between these edges being free to form openings forthe insertion of the ends of the wings 6 in the pocket.

In Fig. 8, I have shown the side walls 23 with the bellows bottom formedfrom a singlerthiokness of material with the pocket produced as in Fig.7, while in this case the side wings 6 are formed from separate stripsofmaterial attached to the side wall Eat the ends thereof.

In Fig. 9, I have shown the side wall i3 of less height than in theother forms of my 7 invention and utilizing an additional side wall 3 towhich the side wall 43 is secured at a point along its lower edge as at37 and along its upper edge as at 28, the portions between such pointsbeing free.

In Fig. 10. I have shown a similar con- ,structiori with the addition ofa strengthening' strip 29 secured to the side walliw' and to theupperedge ofthe side wall 4-3 so as to further strengthen the point ofattachment ofthe upper edge of the wall 43 to said wall 3*. v

Fig. 11, illustrates thesame construction as 'inFig. 10 with theaddition of anext'ension 30 of the wall 3 folded over and secured to aportion of the bellows bottom. 7

is folded on itself 'asat 3l and attached to thevwall 3 whi1e the loweredge of-the latter wall is folded over upon itselfas at 32 and attachedto the wall 53.

' In Fig. 12, the upper edge of the wall 53 I The construction'shown inFig. 13 has the pocket 7 formed between the side wall 63 and thecoacting wall 3 with the latter folded over and secured to the bellowsfold or bottom 4 as in Fig. 11,-but the upperedge of the side 63 is freefrom the wall 3 so that access may he had to the pocket from the insideof the wallet and is normally closed by a flap 33 secured to the insideof the wall 3 which hangs down over the side 63. This flap also preventspapers or articles from entering the pocket when being placed in theinsertion of the free end of the flap 83,

which will eliminate any projecting ends within the wallet compartment.

It is to be understood that the different constructions here illustratedand described are interchangeable so that the difi'erent pocketformations can be used with any one of the different forms of side wingsand the latter may or may not be provided with interlocking devices andstiilening elements.

Of course I do not wish to be limited to the exact details ofconstruction as herein shown as these may be varied within the limits ofthe appended claims without departing from the spirit ot my invention.

Having thus fully described my invention, what I claim as new and usefulis 1. A filing case including sides one of which is provided with apocket, endfiaps or wings carried by one of the sides and havingnonfiexible ends slidably mounted in the pocket.

2. A filing case or wallet including sides,

one of which is provided with a pocket open at both ends and havingopenings communicating with said pocket, end flaps or wings carried byone of said sides entering the pocket through the open ends, said endflaps having stiff ends to prevent their accidental withdrawal from thepocket.

3. A filing case or wallet-including sides, one of which is providedwith a pocket end flaps or wings carried by one of the sides the ends ofsaid flaps projecting into said pocket, and means for securing said endstogether so as to permit a limited sliding movement thereof.

4:. In a filing case including sides, one of which is provided with apocket, end flaps of wings carried by one of 'the sides and having theirends adapted to form a slip joint received in said pocket for securingthe ends together while allowing a limited sliding movement thereof.

5. A filing case including sides, one of which is provided with apocket, flaps car'- ried by the other of the sides, the ends of saidflaps projecting into said pocket, a tongue and locking head formed uponone or said flaps adapted to engage the end of the opposite flap so asto have a limited movement therein.

6. A filing case including sides one of which is provided with a pocketand end flaps or wings carried by the other side with the free endsslidably mounted in the pocket.

7. A filing case including sides connected with an expansible bellowsfold and end wings carried by one of the sides and registeging with apocket carried by the. other s1 e.

8. A filing case including sides one of which is provided with a pocket,a bellows fold connecting said sides and end flaps or wings carried byone of said sides slidably mounted in the pocket.

9. A filing case including single ply sides,

one of which is provided with a pocket,

wings attached to one of said sides and having their free ends slidablymounted in the pocket.

10. A filing case includingsides, a sheet of material disposed acrossone of said sides secured thereto along two opposed edges leaving thesame free between said edges to form a pocket open at opposite ends, andwings carried by the other side with the free ends slidably mounted insaidpocket.

11. A filing case including sides, and another wall disposed across oneof said sides attached thereto along two opposed lines with the materialbetween being free to form a ocket.

n testimony whereof, I have hereunto affiXed my signature.
